Rusty connector in fuse box

[Raffles]

Hi guys,

My air conditioning stopped working. In my quest to find out why, I opened my fuse box under the bonnet. The fuse for the air con is fine, but I spotted the rusty connector in my pictures below. When I poked the rust with a cocktail stick it was all white and gooey underneath. What is my problem and is it serious?

Thanks a lot.

have you removed the connector and examined the terminals?
looks more like grease to me

Is the goo actually dielectric paste?

You have to use special stuff for electrical connectors maybe this isnt the correct stuff just grease ?

Thanks for the replies guys. It turns out it's grease/paste/goo which is to stop the connections arcing. It was done as part of a recall a while ago - apparently there are too many high current connections in a small space. I just got a fright when I saw it yesterday!

Thanks again.
